Age 15Explain it to a 15-year-oldConnect it to the formula
Usage, rates, performance, capacity, rebound effects, repairability and product life affect savings. The rule is Efficiency upgrade payback = incremental installed cost ÷ annual utility and maintenance savings. Its input values are Efficient appliance installed cost, Baseline replacement installed cost, Annual electricity and water savings, Annual maintenance savings, Rebates and incentives, and the main result is Simple efficient-appliance payback. Try changing one number and watch what happens to Simple efficient-appliance payback.
CollegeExplain it at college levelState the model precisely
This calculator evaluates a personal-finance model from stated cash amounts, rates and time assumptions. The implemented relation is Efficiency upgrade payback = incremental installed cost ÷ annual utility and maintenance savings, evaluated from Efficient appliance installed cost, Baseline replacement installed cost, Annual electricity and water savings, Annual maintenance savings, Rebates and incentives to produce Simple efficient-appliance payback. Usage, rates, performance, capacity, rebound effects, repairability and product life affect savings. The result cannot predict markets or include unentered taxes, fees, legal rules, benefits, insurance terms or personal circumstances. Verify material decisions against current documents.
